A Picture Gallery of Pool Design Ideas from World-Class Hotels

The 8,000-square-foot, swimming pool at Four Seasons Las Vegas features two whirlpool spas. Sunbathers who find themselves getting a tad too toasty can summon a spritz of Evian from a nearby attendant. Can't take the heat? There are also shady arbor spots. In case you forgot to pack a swimsuit, the hotel can provide a disposable one (may be limited on design and color).
